Find an equation of the line given one point and the slope. (–10, –5);

allochka39001 [22]

You forgot to provide the slope but here is how you do this

the slope 5 = (y2 - y) / (x2 - x) but we know that (x2, y2) = (-10, -5)
=> (-5 - y) / (-10 - x) = 5 --- multiply both sides by (-10 - x)
=> (-5 - y) = 5 (-10 - x)
=> (-5 - y) = -50 - (5)x --- add +5 to both sides
=> -y = (-50 + 5) - (5)x --- multiply both sides -1
=> y = 5x + 45 --- this will be your equation.

Lily buys a sweater that is on sale for $42, which is 75% of the original price of the sweater. What was the original price of t

allochka39001 [22]

We have an equation: 42/? = 75/100

Cross multiply:
75*? = 42*100
⇒ ? = 42*100/75= 56

The original price of the sweater was $56.

Hope this helps~

Use the Polygon tool to draw the image of the given quadrilateral under a dilation with a scale

Nataly [62]

Answer: See the picture attached.

Step-by-step explanation:

A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".

In this case we know that the scale factor is:

$scale\ factor=\frac{2}{3}$

Since:

$0$

It is a Reduction.

You can identify that the vertices of the quadritaleral are:

$(-3,0),(-9,-3),(-6,-9),(3,-6)$

So you need to multiply the coordinates of eac vertex by $\frac{2}{3}$ in order to get the coordinates of the image.

Then, you get:

$(\frac{(-3)(2)}{3},0*\frac{2}{3})=(-2,0)\\\\(\frac{(-9)(2)}{3}),\frac{(-3)(2)}{3})=(-6,-2)\\\\(\frac{(-6)(2)}{3},\frac{(-9)(2)}{3})=(-4,-6)\\\\(3*\frac{2}{3},\frac{(-6)(2)}{3})=(2,-4)$

Now you can plot the points and draw the image of the given quadrilateral.

See the picture attached.

Please please please help me out :(

Reptile [31]

Answer:

A -4 ≤ x ≤ -2

Step-by-step explanation:

The graph is constant where there is a flat, horizontal line. The graph is flat in the interval -4 ≤ x ≤ -2. This is where the graph will be constant. In all of the other parts of the graph, the y-values are changing. Since the line is flat, the y-value doesn't change.
